Is Indian money a fossil?

Yes, as a matter of fact, the Indian money,is a fossil of a seashell. This fact is very interesting. The reason almost everybody has seen an Indian money, is because it is a very common fossil, not like ones from prehistoric times that are rare. The Indian money is a seashell fossil that takes eons to form.

How can organisms be fossilized?

You fossilize something by having it first fall in rock... then it gets covered in setimentary rock.... most likely and stays over in rock for many years. It then gets covered in rock and hardens and is fossilized!

How do index minerals help geologist?

Index minerals are specific minerals that form under certain pressure and temperature conditions, making them useful in determining the metamorphic grade of rocks. By identifying the presence of index minerals in rocks, geologists can infer the pressure and temperature conditions the rocks have experienced, helping them understand the geological history of an area. This information can be used to reconstruct past tectonic events, infer the depth of burial, and identify the thermal history of a region.

A huge crack in the Earth's surface where anthropologists find fossils to study?

The crack in Earth's surface where fossils are found is called a rift valley. Rift valleys are formed when tectonic plates move apart, creating deep fissures where fossils can be exposed and studied by anthropologists to understand past ecosystems and species. These fossil-rich sites provide valuable insights into the history of life on Earth.

What are the most common animal remains that become fossilized?

  • Fossils are the preserved remains or traces of organisms that lived in the geologic past. Trace fossils are made by marks left by organisms while still alive, such as tracks, burrows, and dung.
  • Decomposition, weathering, and scavenging all contribute to what makes fossils so rare.
  • Almost all fossils are found in sedimentary rock; almost none are found in metamorphic or igneous rock.
  • Fossils are our only direct key to the past, informing us about migratory patterns, weather and environmental conditions, species' interaction, and animal behavior.
  • Scientists use index fossils to place events on the geologic time scale. The organisms that become index fossils are chosen because they had relatively short geologic life spans, wide geographic ranges, and are easily identified.

Scientist have found fossils on the tops of mountain?

The discovery of fossils on mountain tops supports the theory of plate tectonics, as it indicates that these areas were once at lower elevations where fossils could form. Over time, the movement of tectonic plates pushed these areas upwards to form mountains, carrying the fossils with them. This provides evidence of the dynamic nature of the Earth's crust and the processes that shape the planet's surface.

What does materials preserved mean?

Materials preserved refers to objects or substances that have been maintained in their original form or condition over time, often through careful storage or conservation efforts. This ensures that the materials remain intact and available for future use or study.

Why are you most likely to only find fossils in sedimentary rocks?

Most fossils are found in sedimentary rock because it forms in layers so it is easier for the bones or shell of an organism to get trapped between the layers and be preserved. The other two types of rock, metamorphic and igneous, go through much heating and reforming so many remains are destoyed before minerals can preserve them.

Why doesnt everything fossilize?

Not all organisms are preserved as fossils because the conditions required for fossilization are rare. Factors such as rapid burial, absence of oxygen, and the presence of minerals must align to preserve an organism as a fossil. Additionally, the soft tissues of organisms often decay before they can be fossilized.

Have there been any fossils found in Quebec near the St Laurence river?

I've found some before at Parc-du-Haut-Fond. You turn a rock over and chances are that it has a fossil on it! (65%-70%) It's better to look when the tide is low because they are found mostly in the parts that get covered by the water when it's high tide.

I have at least 10 with REALLY NICE fossils on them. I even found a rock with gems in it, but I lost it... :(

Anyway, I hope you can find some! Good luck! :)

The oldest fossil organisms presently known have been dated at approximately how many years old?

Well the oldest living plants are bristlecone pine trees in the White Mountains of eastern California that is 4900 years old.

Oldest Plant in the world-

A team of Tasmanian botanists claims to have found the world's oldest living plant--a vast, low-growing, one-of-a-kind shrub born more than 43,000 years ago. If their conclusions are accurate, this Lomatia tasmanica, a member of Proteaceae family otherwise known as King's holly, would be more than three times as old as the previous record holder, a 13,000-year-old box huckleberry in Pennsylvania.

What are the uncommon modes of preservation of a fossil?

Some may regard uncommon modes of a fossil preservation to be:-

1. Carbon replication of cellulosic structures as in U Carboniferous Plants etc. Also Graptolites in Silurian.

2. "Negative" or "Hollowcast" by solution (of calcareous test) in siliceous bed.

3. Substitution replication by solution effect to Pyrite, Hydrated Silica (flint) or other mineral eg Echinoderma in Cretaceous also wood of tree trunks as in Petrified Forest in Az. USA , also of Ammonites etc in Jurassic

4. "Wrapping" in a Geode, usually with 3 above

How are sites of artifacts and fossils found?

One of the earliest known artifacts in the world are some stone tools left by early human.The ranged from hammer to spears.one stone tools was found in the oegon cave and is said to be over 9000 years old!

How do paleontologists name and classify dinosaurs?

Paleontologists name and classify dinosaurs based on their physical characteristics, such as skeletal features and size. They use a system called taxonomy, which involves grouping species into hierarchical categories based on shared traits. This includes assigning dinosaurs to genera and species based on their unique characteristics and evolutionary relationships.

Where can you find petrified fossils?

Petrified fossils can be found in sedimentary rocks, particularly in areas with ancient riverbeds, lakes, or volcanic ash deposits. Common places to find petrified fossils include national parks, quarries, and coastal cliffs. It's important to note that collecting fossils may be regulated, so it's best to check local rules and regulations before attempting to find or collect them.

Could a fossil found in a river be a fossilized snake?

Yes, it could because that river might not have been there back in the time period of the snake. The snake would have died, became fossilized, then the river formed over. The snake was BEFORE the river.

What is a preserved footprint?

A preserved footprint is a footprint that has been protected from being damaged or eroded by natural processes, such as being covered by sediment or being fossilized. This allows the footprint to retain its shape and structure over time, providing valuable information about the organism that made it and the environment in which it lived.

What period is sometimes called the golden age of trilobites?

The Cambrian and Ordovician periods are often referred to as the golden age of trilobites. Trilobites thrived during these periods, evolving into a diverse array of species and playing key ecological roles in ancient marine ecosystems. Their abundance and diversity make them a prominent feature in the fossil record from this time.

Form of fossilised resin derived from extinct coniferous trees?

Amber is the form of fossilized resin derived from extinct coniferous trees. It typically contains preserved plant material or small insects, providing valuable insights into ancient ecosystems. Amber is often used in jewelry and decorative items for its unique beauty and historical significance.

How were jellyfish fossils found?

Jellyfish fossils have been found in sedimentary rock formations around the world, generally in areas where ancient seas once existed. The soft-bodied nature of jellyfish makes their preservation as fossils rare, but in some cases, the impressions left by their bodies in sediment have been preserved and fossilized over millions of years. Scientists use careful excavation techniques to uncover and study these fossils to learn more about the evolution and history of jellyfish.

Did dinosaurs exist during or after Noah's time?

This All depends on your personal Scientific views.

An answer if you believe in an old earth would be:

No, the dinosaurs all died about 65 million years ago. So they were long gone by the time of Noah. There's geologic evidence of a great worldwide flood sometime between 4000 B.C.E. and 2800 B.C.E. So Noah most likely lived at some point during that time period. As for evidence there is none really, we can't know.

However if you believe in a young earth, an answer would be:

Yes or no. The Bible says nothing of whether there were (or were not) dinosaurs on the ark. You can imagine that since the dinosaurs were so dangerous, men would group together and go kill them. They might have missed some though. You can conclude that since Noah got two (at least) of EVERY animal, then if there were some dinosaurs still left, Noah got them too. As for evidence, there is none on either party.

Can there be a fossil in a obsidian rock?

No, fossils cannot form in obsidian rock as obsidian is a type of volcanic glass that forms from the rapid cooling of lava. Fossils form in sedimentary rocks through the preservation of dead organisms over millions of years.

A fossil created by a print or impression?

A fossil created by a print or impression is called an imprint fossil. Imprint fossils are formed when an organism's remains leave an impression in sediment that hardens over time. This process captures the shape or texture of the organism, providing valuable information about ancient life forms.

Why were fossils of plants found in Greenland?

Fossils of plants found in Greenland suggest that it had a warmer climate in the past when those plants existed. This provides evidence that Greenland was once covered in forests and supported a diverse range of plant life. The fossils also offer insights into the history of the Earth's climate and environmental conditions.

An observer discovers shallow-water marine fossils in rock strata at an elevation of 5000 meters. What is the best explanation for this observation?

The best explanation for this observation is that the area was once underwater and the rock strata was later uplifted to its current elevation of 5000 meters. This suggests plate tectonic activity and the process of mountain building over millions of years.
